Description
Technical field
The utility model relates to a kind of vibrating type roof-bolter that punches in colliery, metallurgical mine, non-metal mine, defence construction and engineering tunnel, be that a kind of, vibration main to rotate to be is the novel vibrating formula rig of assisting.
Background technology
Homemade various pneumatic and hydraulic anchor machine is not survey and draw Australian product the eighties now, does not do any improvement, exists the motor rotor module little, and moment of torsion is little, and reducer double reduction (motor does not participate in slowing down) causes shortcomings such as rotor gear intensity is low.At present, no matter be colliery, metallurgical mine, non-metal mine, defence construction and engineering tunnel hole employed electric bolt machine, Pneumatic anchor rod machine and hydraulic anchor machine, by motor or gas motor, hydraulic motor drive drilling rod after by gear reduction, the drill bit rotation realizes cutting boring, they have a common shortcoming: when drilled object hardness is higher, axial force makes the drilling tool heating, drilled object hardness is high more, axial force is also big more, the stall phenomenon is also serious more, roof-bolter is also just warm more, especially the electric bolt machine can burn motor because of overheated.What utility model patent ZL98250243.5 then protected is that vibration source is the high frequency type vibration brill of spline shell type; Utility model patent ZL200420072813.3 is a kind of novel drilling tool of rolling friction formula, and this tumbling-type friction mechanism can be used for roof-bolter.
Summary of the invention
The purpose of this utility model is exactly that disclosing a kind of is the novel pneumatic and the hydraulic vibration formula roof-bolter of assisting based on rotary cutting, with vibration, improve mechanical strength and the rigidity and the comprehensive technical performance of jumbolter, enlarge the scope of application of this rig, improve drilling efficiency, reduce labor strength and raising drill tool life and improve work situation.
The purpose of this utility model is achieved in that contracted air push rotor rotated one and rotor two, be installed on armature spindle one and the armature spindle two with two keys, needle bearing respectively, armature spindle one and armature spindle two are used respectively on rolling bearing fixing motor housing, the middle cover, bonnet connects with middle cover, shaft gear on the armature spindle one and the gear wheel engagement that is installed on armature spindle two right-hand members, more than each part formed the pneumatic or hydraulic motor of roof-bolter.Below each part formed the vibrating mechanism of roof-bolter: the shaft gear of armature spindle two left ends and the engagement of the duplicate gear on the vibrating mechanism, duplicate gear again with No. four gears engaged that are installed on the power transmission shaft, the rotary power that produces of motor rotor is passed on the power transmission shaft like this.Duplicate gear is mounted on the double crosslinking gear shaft with needle bearing, and double crosslinking gear shaft is fixed on respectively on vibrating mechanism housing and the motor shell.Vibration is applied mechanically thread connection on power transmission shaft, and drill bushing, rolling bearing and drip ring, water jacket and oil sealing also are housed respectively on the power transmission shaft.The vibration cover interacts with the fixedly vibration cover that is fixed on the vibrating mechanism housing, make power transmission shaft in rotation, produce axial vibration again, and pass to drill bit by the drilling rod that is installed on the drill bushing, drill bit is that the mode of assisting is being holed on the soft rock or on half coal petrography based on rotary cutting, vibration.
The utility model has the advantages that conspicuous.One, the utility model is owing to increased the modulus of rotor gear, and the unit area of compressed air effect increases, and the roof-bolter moment of torsion is increased, and penetration rate is faster, brill also darker.Its two owing to change the gear reduction structure, double reduction becomes three grades of decelerations, motor has also participated in deceleration, has improved rotor gear intensity, has prolonged roof-bolter application life.They are three years old, owing to increased vibrating mechanism, make rotating drive shafts produce axial vibration simultaneously, simple rotary cutting has become vibration processing, this has not only improved cutting power, also make drill bit obtain cooling, improved bit life, also enlarged the range of work, improved production efficiency, simultaneously, also overcome roof-bolter stall phenomenon, prolonged the application life of roof-bolter.Because rotary cutting has become vibration processing, smear metal is graininess, and dust is little, has improved the worker laboring environment.The utility model is owing to have above conspicuous advantage, be specially adapted to the bolting with wire mesh operation in colliery, also be applicable to simultaneously the driving of mining, medium and small colliery, Township Coal Mine coal seam are visited water and are visited gas, are applicable to metallurgical mine, non-metal mine, engineering tunnel, highway and orchard water conservancy construction too.
